Struct Filter 

pub struct Filter { /* private fields */ }

High-level filter expression that operates on field names and field=value pairs.

This is the primary type used when constructing filters from user queries. Use Filter::match_field_name() to match any entry with a specific field, or Filter::match_field_value_pair() to match a specific field=value combination.

Filters can be combined using Filter::and() and Filter::or() for complex queries.

Implementations

impl Filter

pub fn match_field_name(name: FieldName) -> Self

Create a filter that matches any entry with the given field name.

pub fn match_field_value_pair(pair: FieldValuePair) -> Self

Create a filter that matches a specific field=value pair.

pub fn and(filters: Vec<Self>) -> Self

Combine multiple filters with AND logic.

pub fn or(filters: Vec<Self>) -> Self

Combine multiple filters with OR logic.

pub fn none() -> Self

Create a filter that matches nothing.

pub fn is_none(&self) -> bool

Check if this is a None filter.

pub fn evaluate(&self, file_index: &FileIndex) -> Bitmap

Evaluate this filter against a file index to get matching entry indices.
